The TJ49150 is a series of 1.5A high performance ultra
low-dropout linear regulator ideal for powering core
voltages of low-power microprocessors. The TJ49150
implements a dual supply configuration allowing for very
low output impedance. The TJ49150 requires a bias
input supply and a main input supply, allowing for ultra low
input voltages on the main supply rail. The input
supply operates from 1.2V to 5.5V and the bias supply
requires between 3V and 5.5V for proper operation. The
TJ49150 offers adjustable output voltages down to 0.8V.
The TJ49150 is developed on a CMOS technology which
allows low quiescent current operation independent of
output current. This technology also allows the TJ49150
to operate under extremely low dropout conditions.
